Using the Put Statement!!

[99mel]

When you use the Put Statement and the text file already contains data (text) it overwrites the data at the position you state. Can I go to a position in a text file and overwrite a certain number but leave the data in front of this number there. The number that I want to write to the file might be longer than the number already in the position.<br>
<br>
Thanks for any help

It sounds like you want to insert into the middle of a text file, depending on whether there's enough room for the stuff you want to Put there.<br>
<br>
Not an easy question, I'm afraid.<br>
<br>
Once you've determined that your data won't fit, you have to go through the following steps:<br>
1) Copy all data from your original file (file 'A') up to the start of the position you want to insert to, to file 'B'.<br>
2) Append your data to file 'B'<br>
3) Back in file 'A', skip over the data that you would've overwritten, then append the rest of file 'A' to file 'B'<br>
4) Delete file 'A', and rename file 'B' to 'A'.<br>
<br>
Ugly, really ugly, but I don't know any other way to handle it. Maybe someone else here has a better suggestion. Of course, the &quot;correct&quot; answer would be to redesign the file layout so this doesn't happen, but that may not be an available option for you.<br>

Hmmm...<br>
<br>
I would suggest that if you get to this point - it's time to use a little database.<br>
<br>
Don't waste your time shuffling data about - it's already been done and far better than most of us could do it. Easy enough to read and write to a database file in VB - even I managed it...<br>
